About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X100-S-U
The AirTAC MBL32X100-S-U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 402 N and pull force of 346 N at 0.5 MPa, making it well-suited for mid-range actuation over a 100 mm stroke. The integrated -S magnet allows CMSG, DMSG, or EMSG sensor switches to detect rod position, while the U flat-end back cover provides a rigid fixed mounting point for straightforward installation.
Unlike tie-rod bodies, this actuator uses a riveted rolling-packed aluminum barrel that crimps the front and rear covers directly to the tube for a lightweight footprint. The carbon-steel piston rod features a 20 µm hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X100-S-U Is Used
PCB Router Z-Axis
Drives the vertical plunge of a desktop PCB routing spindle, using the 100 mm stroke to clear tool changes while the 402 N push force maintains rigid downward feed against the U flat-end mount.
Carton Flap Folder
Folds minor flaps on a small packaging line where the 346 N pull force retracts the mechanism, and the -S magnet triggers a DMSG solid-state switch to confirm flap tuck before sealing.
Connector Insertion Press
Pushes electronic headers into sockets on an assembly fixture, relying on the fixed rubber bumper to absorb the 100 mm stroke end-impact without bouncing the delicate connector.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X100-S-U the Right Cylinder?
If you need less force, step down to the MBL25 bore which provides 245 N push at 0.5 MPa, or step up to the MBL40 offering 628 N if this 32 mm bore is underpowered. The base MBL uses a fixed rubber bumper to soften end impacts; for faster cycling with heavier loads, consider the MBLC variant which features an adjustable air cushion. Note that this standard cylinder does not hold position if air pressure is lost or the valve is centred, so fit an external rod lock or pilot-operated check valve if gravity or drift must be prevented.
This 100 mm stroke is well within the 500 mm maximum standard limit, but even at this length the Ø12 mm rod has limited side-load tolerance. For any offsetting or arcing loads, guide the external mechanism, use a CA pivot back cover, or switch to an MBLD double-rod cylinder to prevent rod bearing wear. Replacement match: 32 mm bore, 100 mm stroke, G1/8 port, PT thread, U flat-end back cover, built-in -S magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL32X100-S-U FAQ
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa the push force is 563 N, and the maximum theoretical force is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-800 mm/s.
No, the base MBL32X100-S-U uses a fixed rubber bumper on the end caps to soften impact, not an adjustable cushion screw. If your application requires adjustable air cushioning for heavier or faster moving loads, you must select the MBLC variant instead.
